Strain-Tuned Nodal Superconductivity in the Charge-Ordered Kagome Metal CsV $_{3}$ Sb $_{5}$

Yusuke Takeuchi, Akito Kobayashi, Saki Uchida +8

The nature of the superconducting pairing symmetry in the kagome metal CsV $_{3}$ Sb $_{5}$ and its relationship with the charge density wave (CDW) order are central unresolved issues. He…

Gap opening mechanism for correlated Dirac electrons in organic compounds $α$ -(BEDT-TTF) $_{2}$ I $_{3}$ and $α$ -(BEDT-TSeF) $_{2}$ I $_{3}$

Daigo Ohki, Kazuyoshi Yoshimi, Akito Kobayashi +1

To determine how electron correlations open a gap in two-dimensional massless Dirac electrons in the organic compounds $α$ -(BEDT-TTF) $_{2}$ I $_{3}$ [ $α$ -(ET) $_{2}$ I $_{3}$ ] and $α$ -(BEDT-TSe…

Fragment-orbital-dependent spin fluctuations in the single-component molecular conductor [Ni(dmdt) $_{2}$ ]

Taiki Kawamura, Akito Kobayashi

Motivated by recent nuclear magnetic resonance experiments, we calculated the spin susceptibility, Knight shift, and spin-lattice relaxation rate ( $1/ T_{1} T$ ) of the single-compone…

Interaction-induced quantum spin Hall insulator in the organic Dirac electron system $α$ -(BEDT-TSeF) $_{2}$ I $_{3}$

Daigo Ohki, Kazuyoshi Yoshimi, Akito Kobayashi

Focusing on the recently-discovered candidate topological insulator $α$ -(BEDT-TSeF) $_{2}$ I $_{3}$ -- having two-dimensional charge-neutral Dirac cones in a low symmetry lattice -- we co…

Tight-Binding Model and Electronic Property of Dirac Nodal Line in Single-Component Molecular Conductor [Pt(dmdt) $_{2}$ ]

Taiki Kawamura, Daigo Ohki, Biao Zhou +2

Motivated by the recent discovery of Dirac nodal line in the single-component molecular conductor [Pt(dmdt) $_{2}$ ], we propose a three-orbital tight-binding model based on the Wann…
